Evoke Pharma to Present Results From Successful Thorough ECG (TQT) Study of EVK-001 at Digestive Disease Week 2016

Clinical Data Support Cardiac Safety of EVK-001

SOLANA BEACH, Calif., Feb. 17, 2016 -- Evoke Pharma, Inc. (EVOK), a specialty pharmaceutical company focused on treatments for gastrointestinal (GI) diseases, today announced that data from the Company’s successful thorough electrocardiogram (ECG) study of EVK-001, its metoclopramide nasal spray product candidate, were accepted for presentation at Digestive Disease Week 2016. As previously announced, this thorough ECG study demonstrated that EVK-001 did not prolong the cardiac QT and corrected QT (QTc) intervals in healthy subjects across a range of plasma concentrations.

Evoke designed the study in accordance with published FDA and ICH guidance on the clinical evaluation of QT/QTc interval prolongation and the proarrhythmic potential of non-cardiac drugs. The QT interval represents the amount of time the heart's electrical system takes to repolarize, or recharge, after each beat, and prolongation of the interval may increase the risk for cardiac arrhythmias.

Marilyn R. Carlson, DMD, MD, Chief Medical Officer, stated, “We are very pleased with how our product performed in this thorough QT/QTc study and we are excited to have the results accepted for presentation at the upcoming Digestive Disease Week meeting in San Diego. These cardiac safety data provide clinically meaningful information for physicians treating diabetic patients with multiple medical problems, in addition to gastroparesis. We believe that the acceptance of these data for presentation to this important body of GI scientists and clinicians is a reflection of the importance of the cardiac safety profile of new drug formulations.”

The randomized, double-blind, double-dummy, four-way crossover study investigated the effects of therapeutic and supratherapeutic doses of EVK-001 on the QT/QTc interval in 48 healthy female and male volunteers. Moxifloxacin, an antibiotic known to prolong the QT/QTc interval, was included as the positive control.

The thorough QT/QTc study was conducted for inclusion in the New Drug Application (NDA) for EVK-001 to fulfill an end of phase 2 meeting request from the FDA. As stated in the FDA’s guidance, “adequate premarketing investigation of the safety of a new pharmaceutical agent should include rigorous characterization of its effects on the QT/QTc interval.”

The Company is also currently conducting a phase 3 clinical trial of EVK-001 for treatment of symptoms associated with diabetic gastroparesis in women. This trial is expected to fully enroll in the first half of 2016 and allow Evoke to move forward with the NDA submission.
